# NRS-2002 MCP

> Nutritional Risk Screening (NRS-2002) assesses a patient's risk of malnutrition using established clinical protocols. It evaluates BMI, weight changes, food intake issues, and disease severity to give a standardized score and specific care recommendations. Run the complete assessment in minutes.

## Description

Hospitalized patients need regular checks for nutritional decline, but figuring out their exact status can involve checking several different metrics—BMI, recent weight loss, current diet, and how much a primary illness is affecting them. This MCP handles that whole process. It runs on the validated NRS-2002 protocol to give clinicians a clear score and actionable advice based on ESPEN guidelines. Instead of juggling multiple data points across various forms, you feed the patient’s core metrics into this connector. The system calculates the specific component scores—like nutritional status or disease impact—and then combines them for one total risk assessment. When you connect to Vinkius, you get access to this tool right alongside thousands of others, making it a central resource for clinical assessments.

## Tools

### evaluate_disease_impact
Calculates the disease impact score (S component) for the NRS-2002 assessment.

### evaluate_nutritional_status
Calculates the nutritional status score (N component) of the NRS-2002 protocol.

### perform_full_nrs_screening
Runs a complete, end-to-end nutritional risk screening using the NRS-2002 guidelines.

## Prompt Examples

**Prompt:** 
```
Perform a full NRS-2002 screening for a patient with BMI 18.5, 5% weight loss, reduced food intake, and moderate disease severity.
```

**Response:** 
```
The complete nutritional risk screening results in a total score of 3, classifying the patient as High Risk. Nutritional Intervention Required is recommended.
```

**Prompt:** 
```
Check the nutritional status score for a patient with BMI 24, no weight loss, and normal food intake.
```

**Response:** 
```
The nutritional status score (N component) is 0.
```

**Prompt:** 
```
What is the impact of high disease severity on the NRS-2002 score?
```

**Response:** 
```
A high severity level adds 2 points to the total screening score, increasing the overall nutritional risk assessment.
```

## Capabilities

### Calculate Nutritional Status Score
Determines the patient's nutritional level based on intake and physical metrics.

### Assess Disease Impact Score
Quantifies how much a patient’s existing illness is negatively affecting their body.

### Run Full Nutritional Screening
Performs the complete, multi-component NRS-2002 assessment in one go.

## Use Cases

### Admission Screening for Surgery
A surgeon needs to know if the patient is nutritionally stable before elective surgery. They run `perform_full_nrs_screening` with the patient's current metrics and immediately classify the risk level, allowing them to pre-schedule nutritional consults.

### Monitoring Post-Discharge Care
A primary care physician needs a follow-up assessment. They use `evaluate_nutritional_status` with recent weight loss data to track whether the patient’s diet is meeting their metabolic needs at home.

### Assessing Acute Illness Impact
A nurse notices a sudden change in symptoms due to a new infection. They use `evaluate_disease_impact` to quantify how much this acute illness is lowering the patient's baseline health, helping the doctor adjust medication.

## Benefits

- Gets a complete picture in one go. Instead of running multiple checks, you use `perform_full_nrs_screening` to get the total risk score and recommendations instantly.
- Pinpoints specific weaknesses. Need more detail? You can isolate components using `evaluate_nutritional_status` or `evaluate_disease_impact` for deeper analysis.
- Reduces charting errors. It handles complex scoring logic, so you don't have to worry about calculating the S or N component manually every time.
- Provides clinical action points. The output isn't just a number; it suggests specific nutritional support interventions based on established guidelines.
- Saves time at admission. You can quickly assess a new patient’s status using this MCP, speeding up care planning and resource allocation.

## How It Works

The bottom line is, you get an immediate, standardized clinical risk assessment that tells you exactly where the patient stands nutritionally.

1. Provide the patient's current data: Body Mass Index (BMI), recent weight changes, reported food intake, and the primary disease severity.
2. The MCP processes this input by calculating the separate nutritional status score and the disease impact score according to clinical rules.
3. You receive a final NRS-2002 total risk score, classifying the patient’s level of malnutrition risk and suggesting necessary support.

## Frequently Asked Questions

**What is the purpose of this tool?**
It identifies patients at risk of malnutrition during hospital stays by calculating a score based on nutritional status and disease severity.

**How is the risk determined?**
The tool aggregates points from BMI, weight loss, food intake, and metabolic stress. A total score of 3 or higher indicates nutritional risk.

**Does it follow any specific guidelines?**
Yes, the clinical recommendations provided are based on the European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines.

**What specific data inputs are required when I call `perform_full_nrs_screening`?**
You must provide four core patient metrics: Body Mass Index (BMI), recent weight loss percentage, food intake status, and disease severity level. The system uses these four points to calculate the overall risk score.

**Can I use `evaluate_nutritional_status` or `evaluate_disease_impact` alone?**
Yes, you can run component scores separately if needed. Using `evaluate_nutritional_status` gives the N component score, while using `evaluate_disease_impact` provides only the S component score.

**What happens if I miss a required data point when running the screening?**
If you omit critical inputs like BMI or weight loss from the call, the MCP will return an error. You'll need to ensure all necessary fields are populated before attempting any assessment.

**Is this MCP efficient for batch processing multiple patients?**
The tool is designed for single-patient assessments. However, your AI client can iterate through a list of patient records and call `perform_full_nrs_screening` sequentially to process batches.

**Does the output from this MCP integrate with standard electronic health record (EHR) systems?**
The tool outputs a clear, structured score along with actionable recommendations. This data is easy for your agent to parse and map directly into existing patient records.
